States of Matter Quiz

Liquid

• A liquid is a state of matter that has a definite volume but no definite shape.
• Liquids take the shape of their container.
• Liquid particles are close together, but they are not fixed in place. They can move past each other.
• Liquids are relatively incompressible. A large amount of pressure is needed to reduce their volume.
• Liquids flow easily.
• Examples of liquids include water, milk, juice, oil, and mercury.

Gas

• A gas is a state of matter that has neither a definite volume nor a definite shape.
• Gases expand to fill their containers.
• Gas particles are widely spaced and move randomly and rapidly in all directions.
• Gases are highly compressible. Their volume changes significantly with pressure changes.
• Gases flow easily like liquids but much faster, as there is less interaction between particles.
• Examples of gases include oxygen, nitrogen, carbon dioxide, and helium.

Shape

• Shape refers to the external form or outline of something.
• Shape describes the spatial arrangement of points or lines composing a solid object or two-dimensional figure.
• The shape of an object can be regular (e.g., a square) or irregular (e.g., a cloud).
• Shape can be described in various ways, including geometric terms (e.g., rectangular, circular) and descriptive terms (e.g., pointed, rounded).
• The shape of a liquid is determined by the shape of its container; it conforms to the container.
• The shape of a gas is also determined by the shape of its container; it expands to fill the container.
• The shape of a solid is independent of its container and retains its fixed shape.
